Since January 1, 2017, the Centers for Medicare & Medicaid Services (CMS) has authorized payment for CPT codes 99358 – 99359 for prolonged services non-face-to-face (F2F). When used correctly, this is a significant reimbursement opportunity for Home-Based Primary Care (HBPC) providers.

The CMS national payment rate for 99358 is $113.52 (the rate for 99359 is $54.78) with a Relative Value Unit (wRVU) of 2.10. This provides payment for the extensive medical management that occurs outside of the F2F visit. Although the use of these codes offers financial benefits, many practices continue to have concerns and/or questions regarding the services, leading to these codes being underutilized.

To help you receive the appropriate amount of reimbursement for the work your providers are doing under these codes, review the below requirements and apply them when appropriate:

In summary, your documentation should include start and stop times that show a minimum of 31 minutes spent on time directly related to an E/M visit. If the time occurred on a different date than the visit, you must reference the date of the F2F service and include a brief description of how that time was spent (e.g., nature or topic of what was reviewed or discussed).

In addition, CPT codes 99358-99359 cannot be reported during the same service period as the following due to similarity in service. As of 2020, however, prolonged services will be unbundled with transitional care management services, meaning they can be reported within the same calendar month:

For additional reference, the National Government Services (NGS) offers the following examples of appropriate uses of CPT codes 99358-99359:

While these guidelines may seem challenging, you can tackle them by creating a Macro within your Electronic Health Record (EHR) that your providers can use for documentation purposes. In addition, you can create a back-end charge review rule to ensure the work does not get billed out during the same calendar month as other bundled services.

The time you invest in understanding these guidelines will assist in exponentially growing financial benefits for your practice.
